- The columnar crystals were different in length at different intervals and problem like fading still existed after PED treatment. 在停止电脉冲处理后停留不同时间的情况下,柱状晶的长度不同,电脉冲处理钢液仍然存在衰退问题。
- The results show that the microstructure of the ZA alloy lines is the parallel directional dendritic columnar crystal. 结果表明:热型连铸锌铝合金线材的显微组织为定向生长的平行柱状枝晶组织;
- The difference between the sample with high columnar crystal and the sample with high equiaxed crystal has been studied by using the two parameters. 本文应用上述参数对比研究了柱状晶发达与等轴晶发达样品的差异。
- The results showed that pulse current can enlarge equiaxed crystal area, narrow columnar crystal area and refine crystal pure Al ingot. 结果表明:脉冲电流能够扩大纯铝铸锭的等轴晶区、缩小柱状晶区,并使晶粒尺寸细化。
- The results show that the crystal evolutive course of SCCW falls into three phases: equiaxed crystal phase, columnar crystal phase and single crystal phase. 结果表明:单晶铜线材的晶粒演化过程包括等轴晶、柱状晶和单晶三个阶段;
- According to experimental results,the macrostructure of aluminium ingot was modified from large grains with columnar crystals to finer grains with equiaxed crystals using the method. 结果表明,该方法可以细化纯铝的凝固组织,使粗大的柱状晶变为细小的等轴晶;
- The structure of columnar crystals is observed for billets cast without M-EMS,and equiaxed structure for billets cast with M-EMS,in which SDAS decreases obviously with increase of stirring current. 无M-EMS的铸坯接近中心的区域,仍然是枝晶臂发达的柱状晶组织;采用结晶器电磁搅拌,促使铸坯中心区域形成粒状等轴晶组织;随搅拌电流增大,二次枝晶间距明显减小。
- Optimize the technology data ulteriorly,reduce crack on the interior round billet,enlarge the center equiaxial crystal area and shorten columnar crystal face to amend the quality of round billet. 通过进一步优化工艺参数,减少了圆管坯内部裂纹,扩大中心等轴晶区,缩短柱状晶区,使圆管坯质量得以改善,从而提高了圆管坯的穿孔性能,减少钢管内折。
